Fusion 550RF-EU

"Arctic Cooling did manage to create a very quiet PSU which delivers stable output combined with a high efficiency. "

"A great PSU which performed well above and beyond my expectations"

"One of the best PSU on the market"

Data Source:

High Energy Efficiency

The PSU is highly powerful and energy efficient.
A test conducted by tech-review shows that the power consumption of the Fusion550 under Windows is the lowest in the field.

Data Source:

Silent Performance

The PSU is equipped with an 80mm ARCTIC F8 Pro fan. A highly efficient cooling design combined with the patented vibration absorption ensures silent operation and low temperatures at the same time. A test done by Planet 3D has shown that the Fusion 550 creates 21dB(A) only even at 110% load.

Safe and Reliable

The Fusion 550 is filled with a number of safeguards to prevent damage to the unit and your precious PC, namely powerful input and output filters, thermal protection, ripple control, precision voltage regulation, over voltage protection (OVP), short circuit protection (SCP) and over power protection (OPP ).

Save Money

"Thanks to the integration of energy efficient ECO 80 technology, it's not a Power Supply Unit, it's a Payment Saving Unit!" commented Quietpc.com.
